RIP sends routing-update messages at regular intervals and when the
network topology changes. When a router receives a routing update that
includes changes to an entry, it updates its routing table to reflect the new
route. RIP routers maintain only the best route to a destination. After
updating its routing table, the router immediately begins transmitting
routing updates to inform other network routers of the change.

Authentication Required

None: No authentication.

Password: A password authentication key is

included in the packet. If this does not

match what is expected, the packet will be

discarded. This method provides very little

security as it is possible to learn the

authentication key by watching RIP packets.

MD5: MD5 is an algorithm that is used to verify

data integrity through the creation of a 128-bit

message digest from data input (which may be a

message of any length) that is claimed to be as

unique to that specific data as a fingerprint is to a

specific individual.

Authentication Code

Password or MD5 Authentication key.
